Bug #: 55349
Summary: arm-linux-androideabi-gcc-4.6: Internal compiler error
compiling libpng in debug mode
Classification: Unclassified
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: ibenrun...@gmail.com
Firstly: ndk-build doesn't give output of which version of gcc it is using but
looking in the toolchains folder I checked the version number of what I believe
it is running:
arm-linux-androideabi-gcc-4.6 (GCC) 4.6 20120106 (prerelease)

Here is information regarding the issue, which should be enough to reproduce
the problem:
Please describe the problem in detail, with the following information (if
applicable)
Host OS:Linux
NDK tools version: tested with android-ndk-r8b and android-ndk-r8c
STEPS TO REPRODUCE:
(Tested using android-ndk-r8b and android-ndk-r8c, libpng 1.2.38 and 1.5.13)
1.Setup simple NDK dev environment with libpng 1.5.13
2.run NDK_DEBUG=1 ndk-build
3.build will fail
EXPECTED RESULTS:
For libpng to compile successfully (which it does when NDK_DEBUG is set to 0)
OBSERVED RESULTS:
Compile thumb : png <= pngrtran.c
jni/png/pngrtran.c: In function 'png_do_rgb_to_gray':
jni/png/pngrtran.c:3418:1: internal compiler error: in reload, at

make: *** [obj/local/armeabi/objs-debug/png/pngrtran.o] Error 1
^It is therefore reasonable to conclude that this is a bug within NDK or
perhaps the version of GCC it is using.
